"No not at all, obviously as a player and obviously from my time of coaching, no I've never heard of performance enhancing drugs in the A-League."

"I'm stunned, from the point of view from football I would be extremely surprised."

"Obviously those sorts of things are kept very, very private if they actually occur, there's absolutely no hint what so ever that anything like that's occurred.

"From an Australian perspective we don't like cheats, we don't stand for cheats."

Jets forward Ryan Griffiths was also surprised by the drug revelations.

But he is confident the Jets are clean.

"This club in particular 100 per cent nobody's taking anything," he said.

"We've got great staff here monitoring all those things and even little anti inflammatories that we're taking they're all clear and the doctors make sure they check all those types of things.

"So in this club we've got a very good monitoring process and I definitely I believe no body here is involved in things like that."

Griffiths says he cannot understand why any footballer would need to take performance enhancing drugs.

"I don't see an advantage in anything for a footballer," he said.

"I know when (Diego) Maradona was caught, I think it was in the '70s, there's no real reason for him to be on it, because the way that the game is played and the size of the players, all those type of aspects you don't really need those type of drugs to enhance your performance.

"I've been involved in the game professionally for almost 20 years and I've never been approached about using a drug or anything like that."

The Crime Commission's report also included details of an investigation into a $40 million off-shore gambling plunge, relating to one Australian sport.

Football Federation Australia chief executive David Gallop has declared there is no investigation into match fixing in the A-League.

He says soccer has been cleared of any wrong doing.

Ryan Griffiths says he is not surprised by match fixing allegations which have surfaced in Europe this week.

"Sometimes when it comes to the mafia and things like that it goes a little bit deeper," he said.

Sometimes if a players gets involved with the wrong crowd, he owes somebody something, a gambling debt or whatever it maybe there's always going to be those types of things.

"What I don't understand is the wages those players are on is ridiculous, they're earning so much money why would you even think about gambling and that's where I think it does go deeper in terms of threats and things like that."

You have no doubt been hearing a lot about the Paris Agreement and know that it pertains to climate change, but are too embarrassed at this stage to ask for an overall explanation of what it's all about.
